e9ea1255c0 This patch adds the following to the FTI module:
* The ability to index more than one column in a table with a single
trigger.
* All uses of sprintf changed to snprintf to prevent users from crashing
Postgres.
* Error messages made more consistent
* Some changes made to bring it into line with coding requirements for
triggers specified in the docs.  (ie. check you're a trigger before casting
your context)
* The perl script that generate indices has been updated to support indexing
multiple columns in a table.
* Fairly well tested in our development environment indexing a food
database's brand and description fields.  The size of the fti index is
around 300,000 rows.
* All docs and examples upgraded.  This includes specifying more efficient
index usage that was specified before, better examples that don't produce
duplicates, etc.

938236a297 The fti.pl supplied with the fulltextindex module generate ALL possible
substrings of two characters or greater, and is case-sensitive.

This patch makes it work correctly.  It generates only the suffixes of each
word, plus lowercases them - as specified by the README file.

This brings it into line with the fti.c function, makes it case-insensitive
properly, removes the problem with duplicate rows being returned from an fti
search and greatly reduces the size of the generated index table.

It was written by my co-worker, Brett Toolin.

5bb2300b59 Revise handling of oldstyle/newstyle functions per recent discussions
in pghackers list.  Support for oldstyle internal functions is gone
(no longer needed, since conversion is complete) and pg_language entry
'internal' now implies newstyle call convention.  pg_language entry
'newC' is gone; both old and newstyle dynamically loaded C functions
are now called language 'C'.  A newstyle function must be identified
by an associated info routine.  See src/backend/utils/fmgr/README.
